Application tiled March 3, 1910. Serial No. 547,117.

in miners lamps and particularly to that type embracing means for generating and consuming acetylene gas.

An object of this invention is to produce a compact generator and consumer of the genera shape of lamps now employed by miners by suspending the said lamps from their caps or from other ortions, of their garment and the purpose 0 this invention is to produce novel means for associating the carbid contamer. the IN uld container and the burner in such relation as to cll'ect an automatic delivery of the liquid to the carbid holder, means being also provided for accelerating or an menting'flie supply of liquid to the carbi upon proper manipulation of a portion of the apparatus, as will be presently explained.

- A still further object of this invention is to produce a cal-bid holder and liquid supply therefor and a novel arrangement of sitters or screens interposed between the carbid holder and the burner for consuming the gas whereby the dogging of the conduit or pipe aml the burner tip is effectively prevented, means being also provided for renderin the parts 'just described readily accessible or the purpose of removing deposits of foreign matter therefrom.

Furthermore, an object of the invention is to produce an a paratus of the character noted having a re ector removably secured in relation to the burner or tip and adapted I to be used in the usual manner.

lVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding partsin the several views, in whic 1- Flgure 1 illustrates a view in side eleva- ,tion of an apparatus embodying the invention; Fig. 2 illustrates a vertical sectional I view of the lamp. Fig. 3 illustrates a horitaken one line corresponding to the line 12-42: of Fig. 2.

In these drawings 4 denotes the base which is also the carbid holder or container, the said base having an external annular shoulder 5 serving as a seat for a packing vring 6 and further a portion 7 above the shoulder forming the mouth of the base which portion 7 shown in the form in Fig. 2, is screw threaded.

There is a liquid container associated with the base and it comprises in its construction a receptacle 8 having a flange 9 extending a suitable distance below the bottom 10 of the receptacle. the said flange being flared as at 11 fol-the purpose of embracing and l bearing against the packing ring 6. whereas a portion of thesaid flange between the flared portion 11 and the bottom 10 of the receptacle is threaded to engage the screw threads of the portion 7, of the base. The flange is also shaped to form an annular shoulder 12 which forms a seat for the textile strainer 13 shown in Fig. 3 as being in the shape of a disk. In addltion to the textile strainer 13, I prefer that a metallic sieve 14 shall lie-in contact with the surface of the textile strainer and when the parts are in assembled relation, the upper edge of the member 7 of the base will serve to hold' the sieve and strainer in position between the upper edge of the member '4' and the annular shoulder 12.

As shown in the drawing, there is a tubular extension 15 leading from the bottom 10 to the carbid container, the said tubular extension being in communication with the liquid receptacle through the bottom 10 of said receptacle. The tubular extension is is movable longitudinally of the tubular extension and is designed to extend into the cat-bid container; said rod being smaller tlnurtlie tube in order that liquid may pass through the tube. B manipulation of the rod just mentioned, tecarbul may be agitated to some extent. The chief function. however, of the rod 16 is to retard the llow of li uid from the li uid rcce tacle to the carbi fl. The flange o the liquid receptacle supports a cross-bar 17 which cross-bar confines an auxiliary textile screen 19 and holds said screen at. the inner end of the conduit or tube 18 for the purpose of preventing acfurther provided with a small rod 16 which I zontal sectional view on an enlarged scale cess of material other than that to be consumed from entering the burner. As shown suitable suspending means, but I have shown the same as being provided with a hook 22 such as is usually employed in miners lamps.

The mouth 23 of the liquid receptacle is threaded to' receive the threaded cap 24:, and the said cap is provided with a flange 25 for engagin a packing ring 26. There is an annular s oulder 27 externally of the liquid receptacle against which the packing ring is forced by the flange 25.

By referrin to Fig. 2, 1t will beseen that the top 28 of t e cap is provided with an aperture 29, and said cap is slightly convexed and it is the purpose 0 the inventor to make this top of flexible material which will nor mally assume the position in which it is illustrated. The top, however, may be flexed to an extent by pressure on the top thereof and the action just describedcislelied upon to augment the flow of liquid to the carbid container. When the supply of liquid to the carbid container has been found insufficient, the operator may press on the top 28 and at the same time close the aperture 29 and when the said to is pressed downwardly there willvbe su cient compression of the air contained in the liquid receptacle to force a slight amount of liquid throughthe tube to the carbid container and as the said top will assume its normal position.

By reason of the fact that the apparatus is of the sectional type, the parts are readily accessible for the purpose of renewing the supply of carbid or liquid or for the pur- 5O pose of cleaning the appara is or for the renewal of parts that have b ome impaired in use.

I claim 1. In a generator, a burner, a base for between the base and the said pipe, means for sup lying liquid from the receptacle to the car id, and a cap for said receptacle having a flexible top provided with an aperture.

2. In a generator, a burner, a base for containing ,carbid having a threaded port10n, a liquid receptacle having a flange threaded thereon, a tubular extension in .communication with the liquid receptacle and the base, a rod slidable'in the tubular extension, a pipeor conduit in communication with the base, screens interposed between the base and the pipe, a nipple for the pipeya cap for the liquid receptacle and a flexible top for the cap, said top having an aperture therein.

3. In a generator, a burner, a base for containing carbid having a threaded portion, a liquid receptacle having a flange threaded thereon, a tubular extension in'communication with the liquid receptacle and the base, a rod slidable 1n the tubular extension, a pipe or conduit in communication with the base, an annular shoulder formed on the flange, a strainer between the base and shoulder, a cap for the liquid receptacle, and a flexible top for the cap, said top having an aperture therein. 2
